ABSTRACTNow, with the development of domestic military science in our country, many high-energy materials such as propellants have been stably produced, some of our special propellant still need to be imported abroad. Including propellant 5/7SFL for the 23 mm artillery cartridge ZU-23, this is a phlegmatized propellant. In this article, the authors will present the technology for the production of semi-finished propellants (before phlegmatization) on the Z production line and this domestic domestication technology, which will make it possible to discharge for the 23-mm cartridge mentioned above.
